My truck in my sig recently deleted but the EGR equipment is not removed yet, just unplugged. I have a steep driveway and either have to park nose up or nose down. When I park nose down and start up the engine in the morning I get puff of blueish smoke indicating engine oil was in one or more cylinders. If I park nose up I don't get the blue smoke. Years ago if you had some blue smoke (gas engine) at startup it was an indicator that you had valve seals leaking. I would assume that it could be the same on a diesel, but why only when parked nose down? What else could be leaking oil into the cylinders while parked overnight in a nose down attitude? The truck has 119K miles on it.

Must be only a certain valve(s) that the guides are bad enough on to leak past into the cylinder. I did my valve guides the first head gasket failure cause of a bit of blue smoke on first start. But I had closer to 200 k on the truck.

This is a strange beast. I started it the other day (nose down) and got no smoke. Oil consumption is very little, everything else seems normal. I guess I'll just wait it out and see what happens.
